lle itlinown that we, Amit SpHonLacnrn and Hmm' C. Bassr.. both citizens ot' the Hineelianifnn illustrated in the accompanying drawings, iii which- Figure l is a side elevation of the inachine: Fig. :2 is a top view of the saine with the cover removed; Fig. 3 is an enlarged section taken along the line 3 3 in Fig. 1; and Fig. 4 is un enlarged section of the controlling gate inthe uctiou pipe taken on the line 4--4 in Fig. l.

Like numerals of reference indicate like parts throughout the several views. i y

The frame 5 is .formed in a convenient size and shapeto support the working parts, and the rollers 6 are joui-nailed in suitable housingsl T on the end portions of said frame and provided to prevent any wear on thc carpet which would beproduced if the carpet was drawn over the corner portion of the frame'. The two pairs .of feed rollers. consisting of the rollers it, l), l() and 1l. nia be caused -to rotate in either direction b v means of the `tight and loose pulle vs.12 on the extended end of the journal of the roller so that a carpet may be fed into the machine from either side. The rollers S and 10 are geared to turn in. unison by means of "the sprocket gearing 13 (Figs. 1 and 2) and the rollers 9 and 11 are journaled inV adjustable hearings 14 so that the proper tension ma v be produced between each pair of hrollers to feed the di-Ilerent thickness of' carpets it may be desired to clean.

Between the pairs of feed vrollers and near each of such pairs is a rotar)` ln'ush 15,. journaled in suitable bearings 11" at itsends kin the frame 5 and actuated b v means of a ybrush. l-laclrrotary brush adapted to be rotated in leither direction by "leans of a suitable countcrsliafl (not shown) and belt ing (not shown). v

A rigi 'ly secured perforated sheet 18 extends across the distance between the rotary brushes to support the carpet while it is being'beaten b v the beating apparatus, which .consists of a shaft 19 journaled in suitable f l housings :20 on the end portions of the frame .3 and the radiallyvextending beaters 2l, which are made of a flexible material, such as leather straps, and made to rotate in either direction by means of the tight and loose pulleys 22 and snitablc belting (not shown). l Y

A suitable inclosing casing; comprising the substantially V-shaped basket :23 and the cover portion Q4, and provided with the narrow openings 25 extendin longitudi iially between such V-shaped has 'et and such" covcrto allow a carpet to enter and pass out of said casing, is secured in the frame 5 to inclose the cleaning mechanism, sothat. the dust and dirt freed from such carpet will be collected and conveyed ontof the machine hv means of the, exhaust fan 26, which is situated iii a convenient position' outside of the machine and connected therewith b v a suitable conveyer pipe 27. v Said convever pipe is extended through the length of the -iuaehiue in the lower part of the V- f sha )ed basket and provided with the longitudinally extending openings :2S in that portion of said convever pipe situated in said V-shaped basket to connect said exhaust, fan with said inclosiiig casing.

Situated near the central portion and extending longitudinally through the length of the, machine immediately beneaththe perforated sheet v18, the vacuuniicleaiiing device, which consists ofthe tube '29 provided willi the nozzle portion haiing the narrow longxtiuhnall. extendnir opening 31 in its upper edge to draw the t ust and dirt 100 from a carpet as it is passed over the perfo rated sheet 1S. The exhaust fan '2G is connected with the vacuum cleaning device b v means of the tube :'9 heiu-gextended out of thc V`shapcd basket joined to the con- 105' jductoi' pipe QT. g

The corresponding amounts4 of air drawn through tlieetubes :'T and 29 may 'be varied :by means of the slide yfate 32 (Fig. il which is situated in a convenient position in sato 1.10

'onductor pipe 27, such as indicated at Y3L-4, e cover portion 24 is provided` with the Adoors 33 covering openin through which the, onerationfof the machine may be -observed and any adjustments made.

The operation of our machine is asV follows :-`-The pulleys 12, 17 and 22 are operatively connected with proper countershafts (not shown) by means of suitable belts (not shown) 1n a manner to allow them kto be driven in either direction so that the workl may be fed into the machine from either The exhaust fan is connected yto a proper countershaft to be driven in one direction in the ordinary manner. f Suppose :ifk

carpet is fed into the feed rollers 8 and 9,

, after passing such feed rollers it passes through the rst openinir 25, over the first rotary brush l and on t .e perforated sheet 18 where it is acted upon by the vacuum cleaning device and .the beaters 21, then' y passes over the second rotary brush and out through the second opening 25 and the feed rollers 10 and 11. The machine may be reversed and the carpet passed through Vas many times asdesired. 'llie air ladened` with the dust and dirt :treed` from'the'carpet by the brushes and beaters is dra wn from `the inclosing casing through the -openings 28 t and conductor pipe 27 into the exhaust fan 26 and forced out of the ioorn as desired,4 The relative amounts of air exhausted through the vacuum cleaning device and the conductor pipe 27 is controlled by throttling the passage -of air througlithe conductor tube 27 by means of the sliding gate the vacuum being increased in the vacuum cleaning device and the suction reduced in the conductor pipe 27 asthe-sliding gate is' closed and the oppositebecouies true as said sliding gate is opened.

What w claim :is new and desire to se-- curcbyLetters Potent, is-

1. A carpet cleaning machine comprising a fra-mc. a plurality of feed rollers mounted in said frame and adapted to feed the work into either side of the machine, a plurality of rotary brushes mounted in said frame in parallel relation with said feed rollers. 'a Alongitudinally extending perforated sheetsecured in the central portion of said frame, a rotary beater mounted in said frame over said perforated sheet to beat the work as it .ing elements, a conductor Y have signed our naine is passed over said perforated .slieeit, :lk

vacuum cleaning nozzle secured in said fraine to act upon the, Work as it is. assed` over said perforated sheet, a casing lnclosi.

ing said cleaning elements,a means for ex-f hausting the air together with the dust and dirt ieed from the work from said casing, a i

means for operating said rae-num nozzle, 'l

and a means for imparting motion to said rotary i 65, g

feed rollers, 'rotary brushes and beater, substantially as set forth. Y y

2. A carpet' cleaning machine comprising a frame, a pair. of feed rollers mounted in each side of said frame and adapted to 'feed the workinto either side of the machine, .a A i rotary brush-mounted in said frame in parallel relation with andnear each pair of feed rollers, a longitudinally extending perforated sheet secured in said frame between said rotary brushes, a shaft mounted in said frame above said perforated sheet having its axis in parallel relation with that of the rotary brushes, a plurality of radiating..

flexible heaters aving one end of each se cured to said :shaft and their other ends `adapted to heat the work as it is passed oversaid perforated sheet, a vacuum clean-4 mg nozzle secured in said frame'under said perforated sheet in a manner to act upon the work as it is being` passed over saidk p erforated sheet, a casing inclosing said cleangitudinally extending openings and situated ipe having lonv iii-the lower,'portion of said casing and n adapted .to be connected with a means for exhausting the air together with the dust and dirt freed from the Work from said casing, :i pipe connecting said Vacuum nozzle; with said conductor pipe, a throttlingj means situatedin said conductor pipe in a. manner to vary tlieaelative amount of vacuum produced in said vacuum nozzle and said ,:on-
